IMPROVEMENT IN MECHANISM FOR THREDING SHUTTLES.`

Specification forming part of Letters Patent No. 71,413, dated November 26, 1867,

Toall whom 'it may concern:

y `Be it known that I, LEwIs RIPLEY, of North Chelmsford, in the county of Middlesex and State of Massachusetts, have invente-d a new and Improved Shuttle Threader and I do "hereby declare that the following is a full,

clear, and exact description thereoffwhich will p enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

Thedrawing represents a vertical section of my improved device for threading shuttles.

1 `The object of the invention is to furnish a `device for threading shuttles which shallob viate the old method of drawing the thread through the eye of the shuttle by suction.

through the application of the mouth, which is attended with unpleasant and deleterious effects by inhaling dust and iiber into the lungsof the weavers.

' -This improvement consists in applying the end of a suction-tube to the eye of the shuttie, `which tube is attached to a piston in a cylinder, and is operated in such manner that a vacuum or partial vacuum is created in the tube, by which the thread is drawn .through the eye of the shuttle to thread it, as hereinafter more particularly described.

A represents a metal cylinder, to be secured by lugs a a, or otherwise, at some convenient part of the loom, near the weaver. B is a piston attachedrto a tubular rod, C, that passes through the head of the cylinder, and works in an air-tight collar, b, on the-head c. The spiral spring D is placed within the cylinder,

month-piece or cushion, e, made of india-rubber or other soft elastic material adapted to the surface of the shuttle, over the eye, as represented in red. i

By apply the eye of a shuttle to the mouthpiece e and pressing the tube G down so as to move the piston, a draft or suction is produced to :fill` the vacuum following this movement, which draws the thread through the eye of the needle in the same manner that itis usually sucked through by the mouth of the weaver. A wire-gauze guard is placed within the mouth of the tu be to prevent the thread from going too far into it.

The suctiorrtube may be operated in various ways to create the necessary draft `by which the thread shall be drawn through the l eye of a shuttle to thread it.

What I claim as new, and desire to secure by Letters Patent, is-

The combination of the cylinder A, piston B, tubular rod G, spiral spring D, and elastic mouth-piece e, constructed and arranged to operate as herein shown and described.

The above specification of my invention signedby me this 7 th day "of May, 1867.
